7.26 an ic inverter fabricated in a 65-nm cmos process is found to have a load capacitance of 3 ff. if the inverter is operated from a 1.2-v power supply, find the energy needed to charge and discharge the load capacitance. if the ic chip has 5 million of these inverters operating at an average switching frequency of 2.5 ghz, what is the power dissipated in the chip? what is the average current drawn from the power supply?
